Case necks collapsing when seating bullet
rock,roll,n,load
Member Posts: 698 ✭✭✭✭
Hi, maybe you guy's can help me out. I am trying to load some .338-06 rounds and I am running into a problem. When I try to seat the bullet, it goes in about 1/8" then the neck collapses. I am using Federal .270 brass, ran them through RCBS dies. Trimmed them to the correct lenght, chamfered and deburred the cases. I miked the bullets, they are .338" I miked the ID of the sized case and they are running .335"-.336" The sizing die runs .337" The case wall thickness is running .015" I am making sure the bullet is square before seating. Should I lube the bullet before seating? Do the necks need to be turned? I have done a good bit of loading including Wildcat's and never had this problem before. Any help would be appreciated.
Thanks, Jim (jmh7@atlanticbb.net)
P.S. I tryed a few rounds made from .30-06 brass and run into the same problem.

I was crushing 6.5-06AI's when I first loaded for the rifle and couldn't figure out why,...it was the seater die body. Wish I knew that ahead of losing a handful of Lapua brass[V]
Problem solved. Apparently it WAS operator error and the die was adjusted wrong. I backed off on the seating die and it worked fine. I guess the die body was pushing it back. So I went back to square one and started from scratch, setting everything over and now producing good reloads. The .270 brass and the '06 brass both work fine. Thanks for the help!
